Depends on exactly what you mean --- the most common method is to make a Full & Final Offer" (F&F). This is paying a lump sum based on the amount of payments left to pay (which is usually rounded down a little). It has to be from a 3rd party (which will be checked) and will bring th IVA to a close. However your credit files will still be rubbished for the full 6 years.
